SPECIFICATION forming part of Letters Patent No. 537,002, dated April 9,1895.

Application tiled October 15 1894.

To all whom it may concern: f

Be it known that I, CHARLES A. BONNEY, of Brockton, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovement in Seam-Markers, which will, in connection with theaccompanying drawings, be hereinafter fully described, and specificallydefined in the appended claims.

The object of this invention is to produce a machine that can be quicklychanged as desired, so as to be in condition to seam mark any size ofshoe that may be presented for such purpose; and the invention consistsin a machine provided with a base, to be secured to the bench, havingtwo standards rising therefrom and supporting a girt secured at the topofsaid standards; with a spring supported vertically movable partarranged to be depressed by means of atreadle, on which as also on saidbed are arranged curved guide- Ways in which are arranged bent strips ofthin elastic metal which when brought together impart to the leatherplaced between them the mark shown in Fig. 6, as will be again referredto; stop gages being provided against which the shoe upper is placedwhen being marked; and one endof said strips of bent elastic metal beingsecured to a slide arranged to be moved on a dovetail so as to adaptsaid strips 'of metal to mark shoes of any desired size; mechanism to bedescribed, providing for sliding and locking said slides and strips atany desired point, according to the size of shoes to be marked, all aswill be next herein explained and then specified in the claims.

1n the drawings, Figure 1 is a top plan view of a machine embodying myinvention. Fig. 2 is a front elevation of the machine shown in Fig. l,the top girt and the movable section being broken away at one end toshow the construction. Fig. 3 is a sectional plan view, the sectionbeing horizontal and taken on line y, Fig. 2, and the view being fromabove that line. Fig. 4 is an inverted or A under-side plan view, fromline y, Fig. 2, up-

ward. Fig. 5 is a vertical section taken as on line cc, Fig. 3, andviewed as from the right in that ligure. Fig. 6 is a side elevation of ashoe upper as marked by my machine.

Referring again to said drawings, A represents the base of the machine,provided with senti No. 525,907. (No model screw holes a, a, by which tosecure it in place when in-use. At the respective ends of said base aresecured the standards B, B, on which, at the top, is secured the girtC.V Between said base A and said girt C is arranged the intermediatepiece D mounted on said standards B and cushioned by the helical springsb, while the lighter springs c arranged between D and girt C relieve Dfrom shock whenit is released and rises by force of springs b. l

Arranged above bed A is the elastic curved strip olmetal d, which at itsrearward curve is arranged between the curved bars e, e, secured on saidbed, while the part that curves to the front is secured between thecurved bars g, g, secured to slide h arranged upon dovetail '11 of bedA.

A curved elastic strip f is arranged beneath part D, it being arrangedin position at the part curving to the rear between guides y, t7 that'are secured to D, while the part that curves to the front is securedbetween parts lo, k, that are Vsecured to slide Z that is mounted upondovetail m formed upon D. Said curved strips d, f, are arranged to slideas required between e, e, and j, j, but are locked rigidly between theirrespective blocks g, g, and 7c, k, they being heid by` a screw n thatpasses through them and the bars between which they are secured. Uponthe rear side of slide h is a rack p and alike rack q is formed uponslide Z and a' vertical shaft y carries a lower gear t that meshes inrack p and an upper gear w that meshes in rack q so that as said shaftis slightly rotated in one direction rit will move slides h and Z towardguides e and j, thus arranging the' machine for smaller shoes; ywhile ifmoved in the opposite direction said slides are moved farther from saidguides, thus arranging the machine for larger-- For the purpose ofactuating said shoes. shaft y and the slides h, l, and strips d, f, anarm 2 is secured to the top of the shaft which at its outer end carriesa spring pin 3 that en` gages in the seats marked from 4 to 12 in thearc formed at the top of girt C; which seats respectivelyrepresent thenumbers cor- .responding to sizes of shoes that are to be marked in themachine. Y

In use, lever 2 is so placed that pin 3 will rest in the seat whosenumber corresponds to the size of upper to be marked. Then the ICO uppershown in Fig. 6 is placed with its line 13 against gage 14 While toepart 15 bears against gage 16 secured to slide h, which gages determinethe exact position the upper should occupy. rlhen part D is depressed bya treadle (not shown) attached to rod 17, secured to boss 18, formed onD, by which means the two sides of the upper receive from strips d, f,the mark 19 on which the stitching is done. In practice the two halvesof the upper Will be markedin this machine before being stitchedtogether, and both outsides of the upper will be marked at the same timeby the two strips (Lf.

It will be obvious that by means of the ready adjustment of my machineall sizes of shoes can be marked thereon, and this with but a momentspent in its adjustment to the proper size, as the mere moving ot'slides h, I, by the means specified, or any equivalent means, is allthat is required to adjust the machine for any size of shoe. To preventthe bringing together of strips d, f, to their injury at any time, or toprevent marking the leather too deeply, the thin tubes 2O are arrangedon standards B inside springs b to stop the approach of part D at theproper point.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a seam marking machine of the class specified, the thin elasticcurved strips secured to a slide at one end and arranged to move betweenguides at the opposite end, with means for moving said strips to adjustthem to the size of shoe to be marked, substantially as specified.

2. In a seam marking machine the combination of flexible strips d, f,arranged in guides as shown and actuated by slides 7L and d, mounted onguides, substantially as shown, the racks p, q, shaft y with gears w,and means to aetuate and adjust shaft y, substantially as specified.

3. In a seam marking machine andin combination with adjustable markingstrips (Lf, the curved gage 14 and the gage 16, arranged upon slide 7L,substantially as specified.

4. In a seam marking machine the adjustable elastic strips d, f, securedat one end to slides, mechanism connecting said slides with shaft y, anarm secured to said shaft, an are carried by girt C and a series ofgraduations thereon with which said arm can connect as the machine isadjusted to sizes of shoes to be marked, substantially as specified.

5. In a scam marking machine, the base A, standards B, girt C,intermediate section l), mounted on standards B and arranged to beactuated up and down, the flexible strips secured at one end to a slideand arranged in guides, gears by which said slides are connected withshaft y, the arm lconnccted with said shaft and a point 3, connectingwith spaced points on the arc of said girt, all sub stantially asspecified.
